Results of multiple sclerosis :

Expression	No significance
Risk type	Disease risk
Result	Results indicate that MAG gene do not have a significant genetic effect on susceptibility to MS in this population.
Mechanism/Pathway	Myelin proteins that have been investigated as possible target antigens of the autoimmune response in MS and MS-like disorders include myelin-associated glycoprotein (MAG).In addition to the immune-mediated component of MS, an underlying complex genetic susceptibility is a significant contributing factor.Because myelin appears to be a target for the autoimmune attack in MS, genes coding for myelin proteins are potential candidates for involvement in the pathogenesis of MS. Polymorphisms or mutations in coding or regulatory sequences of these genes could hypothetically promote autoimmunity if they modify the expression, turnover, or function of myelin proteins.
